Regression Analysis

Regression Analysis is a set of statistical processes for estimating the relationships between a dependent variable and one or more independent variables.

The term regression was originally applied to describe biological processes which ‘regress’ toward normative values. Today, we can think of data points regressing toward a mathematically derived normative line or shape.

For example, in the diagram below, the linear regression line represents a dependent variable y based on the independent variables x.

Examples of Regression Analysis Functions

Examples of types of regression analysis include:

Regression vs. Classification

Regression produces continuous number predictions. Classification produces discrete category predictions.
